5.1.3.19 | Chondroitin D-glucuronate |
capsular polysaccharide from Escherichia coli K4 consists of a chondroitin backbone to which beta-fructofuranose units are linked to C-3 of the D-glucuronic acid residues. Removal of the fructose units by mild acid hydrolysis provides a substrate for the chondroitin-glucuronate 5-epimerase |

5.1.3.19 | Chondroitin D-glucuronate |
C5-inversion of D-glucuronic acid to L-iduronic acid occurs on the polymer level. This transformation is greatly promoted by 4-sulfation of neighboring N-acetylgalactosamine moieties |
